We present calculations of the temperature dependence of H(2)O pressure broadening parameters by H(2)O, CO(2), N(2), and O(2). They were made for Q-lines with a theoretical model which provides a correct treatment of close collisions and has been widely tested. The results should be useful for Raman spectra calculations. A simple law is proposed to deduce halfwidths of P- and R-lines from the Q-line results. The accuracy of this law at high temperature is demonstrated. A simple analytical representation of a constant halfwidth approximation is also given.
我们给出了由水、二氧化碳、氮气和氧气导致的水压力展宽参数随温度变化的计算结果。这些计算是针对Q线，采用了一个理论模型进行的，该模型能正确处理近距离碰撞且已得到广泛验证。这些结果对拉曼光谱计算应会有所帮助。我们提出了一个简单法则，可根据Q线结果推导P线和R线的半高宽。证明了该法则在高温下的准确性。还给出了恒定半高宽近似的简单解析表达式。
